Sir: Sites such as Facebook, Twitter, and MySpace can be enjoyable, when used in small sessions. The problem is that they are frequently overused. Within a few clicks anyone on these sites can access anything we post or upload; including a prospective boss or job opportunity. They also prevent children and teens from socialising like they used to, and many are pushed to the point of mental instability. Social media sites are such a waste of time; without them, our society would be much better off. Company managers often use Facebook as a tool to learn about prospective employees. Often times they will look through a possible employee’s Facebook account before deciding to even bring them in for an interview. What people post on Facebook can be a very good indicator of their true character. People tarnish their image by spending too much time uploading unimportant things. When excessive amounts of time are spent on these sites, people have less time or desire to directly socialise with others. People who do not go out and meet others have harder a time accomplishing important social tasks. SADIA MUHAMMAD YAR Karachi
